The present article pertains to nonlinear vibration characteristics and load-carrying capacity of asymmetric structures, employing a single-story model. It is found that torsional response of structures is usually more evident while taking nonlinear deformation into account. Ratio of torsional response before and after members yield is influenced by arrangement, shape of structure, and eccentricity. This paper suggests that there would be three torsion collapse modes for asymmetric structures and gives methods to avoid torsion collapse for each case. The research demonstrates that it is important to take nonlinear torsional response into account while controlling torsional distortion of structures. And it is essential for asymmetric structures to maintain lateral stiffness and torsion stiffness in bi-directions uniformly.
